COVER FOR TIMER WIRES.

Application filed April 3,

This invention relates to a cover for a timer kwire assembly toprevent Athe wires from becoming short-circuited on account of the oil, Water, and dirt which accumulates around the ltimenshell and destroys the insulation on the timer Wires.

An important object of the invention is` to provide a cover of the character above specified which may be readily attached to the timer and which incloses the timer wires in such manner that the latter are shielded against deterioration and at thesame time brought into electrical engagement with the timer. n Y n A further object of the invention is to provide a device `of the character above specified simple in construction, strong and which is believed may be n'ianutactured at a reasonably low cost. c

Various other objects and advantages of the invention willbecome apparent during the continuance ofthe following description.

l In the drawing: n

Ffgure 1 is a view ofthe proposed cover in side elevation.

Figure 2v is a cross sectional View of the cover as taken on line 2 2 of Figure 1, and

Figure 3 is a central longitudinal section taken online 3-3 of Figure 2.

This cover is formed as a flat rigid annular body comprising tivo fibre rings 10 and 11 respectively ei'icircling the back portion of the timer, which is indicated by the dotted line structure 12 of Figure 2. These rings are preferably held together with sealing wax and a suitable number of rivets 13, and are provided'with an offset portion or throat Mover which engages one end of a taper-- ing funnel 15. This funnel is preferably fiattened on the opposite sides of its inner end and is secured to the ring by a rivet 16. To the outer end of the funnel is soldered or otherwise fastened a metallic flexible casing 17 thru which extends the timer wires 18.

The terminal ends 0f Wires 18 are adapted to be enclosed between rings 10 and 11, one of which is suitably grooved as shown at19, terminate at their innermost ends adjacent slots 20 which are arranged at relatively spaced points in the circumference of the rings. Projecting thru each slot is the U- shaped securing end of a contact member 21 which has a right-angle base fitted in a suit` 1922. serial No. 549,182.

able cut-out 22 on the inside ofthe ring. Eachy terminal is connected to' the end of a wire 1S which conducts the currentfrom the timer'to the coil. lVhen the rings are in place on the timer the U-shaped ends of terminals 21 engage over contact posts 23 of the timer, being clamped in place by the binding nut 24.

Thel grooves 19 converge towards the throat portion of the cover at which point the wires enter between the rings. At this point also, the entering wires may be taped to avoid a short-circuit on thefunnel 15.

The cover may be coated with sealing wax on the outside to prevent'oil, water, dirt or grease from accumulating on the wire-ends which are thereby protected from deterioration and so shielded in their connection with the timer as to avoid a short circuit by the accumulation of oil, water etc., as previously y set forth, this coating 25 also aids in holding the disks -11 and 12 in proper position and as already shown in Figs. 2 and 3, 4forms a casing for the cover extending from the funnel 15 around the same, which casing is of flat annular shape and is comparatively thin. The flat contact members 21 have their inner ends conveniently disposed flat against the flat ring 11. y

From the foregoing it is believed that the advantages and novel features of the invention will be readily understood and that further detail description is unnecessary.

that is claimed is:

1. A timer wire assembly and protective device comprising a pair-'of connected annular disks of insulating material adapted to fit in assembled relation over one side of the timer casing, one of said disks having circumferentially spaced slots therein and spaced grooves extending circumferentially from said slots, respectively, to a portion of the edge of said disk, angle plates, each having one portion disposed in said slots, timer wires disposed in said grooves and perma-v nently connected to said plates, sai-d plates each having another portion extending through said disk at right angles thereto and provided with U-sliaped openings at their ends adapted to t over the terminals on said timer casing when said disks areplaced thereon.

2. A timer wire assembly and protective device comprising a pair of connected annular disks of insulating material adapted to .lit in connected relation over one side ot the contact ring oit the timer ot a Ford or similar automobile, said disks having timer Wirei disposed therebetween in spaced relation and extending eircumterentially thereof, circumtercntiallv spaced terminals se cured to the ones of said wires and having U-shapcd clips projecting through and normal to one ot said disks and adapted to embrace the terminals of the contact ring when the disks are placed thereon.

3. The structure set forth in claim Q, ane a cover enclosing said disks and holding them in lined relation.

rlhe structure set forth in claim 2, said disks having alin d laterallyv projecting portions betiveen which said timer Wires pass, and a tunnel member enclosing said portions and adapted to have a Wire containing conduit secured thereto whereby said Wires are completeluvY enclosed.

5. A cover or shield 'tor a timer Wire assenibl'utY comprising a pair ol' liber rings tastened side by side and jointly oli'setto provide a throat portion7 one et said rings having slots arranged at relatively spaced points in its circumference and being grooved to receive the terminal ends ot' the timer Wires, said grooves respectively extending trom the throat portion to one ot the said slots, a tunnel eng geable over the said throat portion to provide a guard extension tor the said Wires entering between the said rings, a contact at the inner terminal o' each Wire, said terminal projecting thru the slot to provide attaching means exteriorl57 ot the said rings, a coating ot sealing Wax or other \vaterpreoling substance enveloping the said rings and the said guard extension, and

means positively connecting the said rings, one to the other and to the guard extension.

(3. A protecting device for the timer wire assembly ot an automobile comprising, a pair ot superposed annular disks ot' insulating material, one ot said disks having cirmunter-entiall7 spaced contact members seated therein projecting laterally therethrough and atapted to tit over the timer contacts4` spaced Wiresl extending circumterentially between said disks and connected to said Contact members at one end and having' their other ends projecting at adjacent points at the .edges ot said disks, a member enclosing the said projecting ends` oi said rfires and a cover for said disks extending from said member around the disks and adapted to hold the disks in position.

7. rthe combination with a flexible conduit having a plurality ot insulated timer wires therein, ot fiat member having diverging sides connected to said conduit, said wires diverging srostantially in one plane in said member, a tiat annular casing securet'l to said memba'7 a thin rigid member in said easing having grooves in which said ivircs are disposed substantially in one plane and extending to points ninety degrees apart therein, means for holding said Wires in said last mentioned membenl a. contact member comprising tiat platesJ bent substantially at right angl-cs secured to the terminal ot' each wire and having one portion secured in said iiat casing and another portion projecting there'tron'i and substantiall)r at right angles to the plane thereof, said projecting portion beingprovided with a slot adapted to lit over the terminal post o' the timer casing.
